Definitions

  • a drum associated with means adapted tofensure itsrotation at a constant speed is provided and to the drum is secured one endof a'iiexible member adapted to be wound on to or off the drum, the other end of the iiexible'member being secured to a insee associated with a second fusee in such manner that both usees rotate at equivalent speeds, one end of'a second flexible member being connected with the smaller end of the second usee and with a: weight or the like means for securing a constant driving eiiort, and a driving connection is provided between the fusees and the turntable.
  • means are provided whereby upon rotation oit the drum in order to raise the weight, the dri ving connections between the drum and the .ieans provided for securing a constant speed, and between the usees and the turntable are released.
  • the driving connection between the fusee and the turntable is also arranged to cause Vthe turntable, the frame ,carryingthe'same and the fusees to travel in a rectilinearpathwith respect to the stylus.
  • a drum is connected through suitable reduction gearingwith a governor adapti 4.3 ed to ensure a constant speed ot operation of 496,277, and in Great Britain VMarch 13, 1930.
  • a positive driving connection is provided between the fusees and the turntable.
  • a toothed wheel adapted through suitable gearing to form a driving connection with the spindle towhich the turntable is secured.
  • the housing or frame for the usees and the drum is slidably arranged on a support and the spindle for the turntable or a spindle from which motion is the case of machines deimparted thereto may in such case be arranged in driving connection with a worm whereby the housing or frame will be moved in a rectilinear path with respect to the stylus at a pre-arranged speed to give the number of cuts per inch required in the record.v

  • the worm wheel 8 is in engagement with the Worm 15 rotatably mounted on the spindle 16 and provided with a dog clutch element 17 adapted to engage the dog clutch element 18, the teeth of these elements being arranged so that on the rotation ofthe drum in the direction of the arrow in Figure 1, the driving connection between the dog clutch elements will be interrupted and the worm wheel 19, which is associated with the dog clutch element 18 will not, in such case, operate the worm 20 the pivots 21, 21a of which are arranged in bearings 22 and 22a and the associated worm wheel 23 which is in engagement with the worm 24 .on the spindle oi the centrifugal governor 25, the pivots of which 26 and 26a are arranged in bearings and 27a.
  • a brake member in the form of an annulus 30 which has a gimbal mounting, being provided with pins 31 engaged in the arm 32 connected to the braclret V33 and provided with an adjusting screw 34.
  • the governor in question operates to ensure that the drum 4 will rotate at a constant speed as the wire rope 35 is unwound from it and wound upon the fusee 36 which, together with the usee 37 and the worm wheel 38, is mounted on the spindle 39, vthe ends of which are engaged in bearings 40 and 40a provided in the brackets 41 and 41m.
  • Thetwo fusees and the associated worm wheel are rotatable at a varying angular velocity corresponding with the conicity of the fusees by unwinding from the fusee 37 a wire rope 42 which passes over the blocks 43 and 44, to the latter of which is connected a weight 45.
  • T ie worm wheel 38 is in engagement with the worm 46 mounted on the spindle 47 on which and on the same spindle rotatable with the said worm is arranged a worm 48 in engagement with the worm wheel 49 rotatably mounted on a sleeve 50 mounted in the bearing member 51 rigidly connected with thc saddle 3.
  • the sleeve 50 is provided internally with a screw-thread engaging the lead screw 52 which is mounted in brackets 53 and 53a on the bed plate of the machine so that by its rotation the saddle is caused to travel on the guides on the bed plate.
  • the worm 46 is provided with a one-way dog clutch member 54 engaging a correspondingly formed dog clutch member 55 which is provided with a key-way 56 engaging the Toodrude keys 57 which also engage the sleeve 58 on which the helical wheel 59 is formed,
  • This wheel engages a corrcsponding helical wheel 60 engaged in a collar 61 supported on a collar 62 rigidly connected with the spindle 63 ot the turntable 64 on which the mould containing the wax for forming the record matrix 65 will be supported and moved relatively to the cutter 66.
  • the wheel 60 and its collar 61 is capable of a limited degree of rotary motion about the spindle, the driving connection between it and the spindle being constituted by a strip of spring steel 67 engaged between the pins 68 and 68a provided on the collar.
  • the cutter which will normally be a device adapted to be operated by sounds through suitable electrical amplifying devices, is sacured in known manner to a fixed head and the table is traversed with respect to the cutter.
  • Rotation of the table is secured by rotating the drum 4 through the intermediary ot the pinion 9 and the toothed wheel 7 so as to wind on the drum the wire rope 35 olf the tusee .3.6.
